文摘

The short-lived 224Ra isotope was measured in coastal water samples from Laizhou Bay, China using a radium delayed coincidence counting system. Based on the horizontal distribution of 224Ra and a mixing model, the horizontal eddy diffusion coefficient was estimated to be 253.1 × 106 and 56.5 × 106 m2/d for the surface and middle layers, respectively. The submarine groundwater discharge (SGD) into the bay was estimated on the basis of the 224Ra mass balance model. The estimate of the SGD into the bay is 4.2 × 108 m3/d, approximately six times the annual average flux of the Yellow River.
